" MbP-BUCKET. Y

Be it knownthat LAUREN A. Cnnriiiqe HAM, a 'citizen of the United States, residing at Omaha, in the 'county of Douglas and State of Nebraska, haveinvented certain new and useful Improvements in -Mop- Buckets,of which. the following is a specifi cation. =1 1 a The present invention-relates toimprovements in mop buckets,-and has for'an'object acter in which are placed wringer rollers for squeezing" the mop therebetween, the rollers being placed at one side of the bucket. so as to allow a free space at'theother side thereof for the" introduction of the mop and its removal if desired without passage through the rollers. A

Another object'of the invention resides in, providing an mproved mop and wringer bucket of'the character above lndicated in which the construction issimple and cheap, and-the "operation of the device ready and efficient- Y With the foregoing and otherobjects in View, the invention will be more fully described hereinafter, and will be more particularly pointed outin the claims appended hereto. I v V In the drawings, wherein like symbols re-' 1 for to like or corresponding partsthroug v tions of the shanks of lag screws 22, which Fig. 4 is a'plan view of a supporting arm Fig. 5 is a longitudinal central sectional view through one of the wringer rollers;

Fig. 6 is a side view of the plunger bracket.

Referring more particularly to the drawings, 12 indicates a bucket which is illustrated to be of the sheet metal type, but it is understood that the invention may be applied to buckets of other constructions and designs. The bucket 12 is provided with the usual bail or handle 13, and according to the invention I furnish the bucket near its base with a foot piece 14 extending from one side thereof in contact with the supporting 2: Specification of Letters Patent.

\ surface sothat the footmay be placed thereupon to steady the bucket and prevent its being raised or tilted when the operator is in the act of drawingthe mopupwardly through thewringer rollers as hereinafter described. Q

Within the bucket near one side thereof is a supporting bar 15 which extends across the bucket parallel with a diameter thereof so that the bar coincides substantially with a chordsub-tending an are on the circle of which the bucket is made. The ends of the bar 15 are bent so as to lie against the walls of the bucket and are secured thereto by rivets or other suitable fastenings 16. The bar '15 is constructed with alug 17 which is cut out from the bodyportion of the bar and bent at rightanglesl This lug'17 is perforated for a purpose to be later described. p

The .bar is also formed with a horizontally elongated slot 18 substantially centrally of the bar, and this slot 18 is formed substantially parallel and oppositeto a similarly elongated slot 19 formed in an arm 20 whichis riveted or otherwise secured to the wall of the bucket as indicated at 21 and are threaded intothe ends of awooden or other roller 23.

. The roller 23 is thus allowed to slide back and forth in-a horizontaldirection owing to the loose fit of the lag screws 22in the slots lSand'19/This permits the roller 23 to move back'a-nd forth withrespect to a companion roller 24 also preferably made of wood, this roller being more particularly seen in Fig. 5 where it is illustrated to be also provided with lag screws 25 being pointed and threaded near their pointed ends. The screws are engaged with the ends of. the roller 24 leaving the heads of the screws projecting a distance from the end walls of the roller in order to be received in perforations made in the bar 15 and a supporting bracket 26 which extends in aline-' ment with the arm 20 and is riveted or otherwise'secured to the bucket as indicated at 27. The roller 24 is thus free to turn about horizontally sliding movement such as that to which the roller 23 is subjected.

The roller 23 is, however, constantly urged toward the roller 24 by means of plunger brackets 28 more particularly illustrated in Fig. 6, which are provided with round perforations 29 to fit about the shanks of the lag screws 22. The brackets are provided with right-angular abutments 30 to which are secured plunger rods or stems 31. One of the plunger rods 31 has a sliding fit throughthe perforation in the lug17 onthe bar 15, while the other plunger rod fits slidingly througha similar lug 32 cut out and bent over from the arm 20.- The plunger brackets themselves slide alongside the bar 15 and arm 20 respectively. Coil springs-33 are wound about the plunger rods 31 between the lugs and the abutments 30 and act to normally urge the roller 23 toward its companion 24.

In the use of the device water or suds is placed in the bucket'12, and after each mopping operation the fabric portionof the mop is introduced through the free space in the bucket at the side of the wringing device which'is clearly shown in Fig. 1. The mop is worked into the suds or water several times so as to cleanse it, and it is afterward passed through the space between the rollers 23 and 24 which will wring it out.

The springs 33 will develop suflicient pressure on the mop to squeeze it, but in case any foreignmatter of a hard nature clings to .the fabric of the mop or any inequalities are found in its structure, the coil springs 33 will permit the roller 23 to yield, thus permitting themop to pass through the rollers without the likelihood of injury thereto.

I do not wish to be restricted to the size, form, and proportions of the various parts,

and obviously changes could be made in the construction herein described without fdeparting from the spirit of the invention, 'it being only necessary thatsuch changes fall within thescope of the appended claims.

What is claimed is: 1. In combination with a bucket, a supporting bar mountedtherein and provided with a slot and a perforated lug bent at substantially ri ht angles from the bar away from the adlacent'side' ofthe bucket, a pair of arms extending-across substantially the central part of the bucket and lying approximately parallel with said bar whereby to'leave a large space at the the other side of said arms away from the bar clear, 'one'o'f saidwwsbeingproeided with a slot therein and a perforated lug 'bent toward said first mentioned lug, a pairof rollerspronided with trunnions' extending therefrom, the trunnions of one arojl'ler being fitted in one of said arms and .the the .trunnions oi the other lmller beingslidab1yfitted in :the

slots in the other arm and bar, plunger b c connect d to the lr'u'nni ns mounted;

in said slots and having abutments, rods with a slot and a perforated lug bent at substantially right angles from the b, a pair ,efarms extendmg substantial ailmement across the central partiof the bucket and lying ,aproximately parallel with said bar and one of said arms provided with-a slot therein, a {pair of ,wooden ;rollers,.Elag screws removahl y fitted in the ends v:of said rollers and having the heads spaced from said ends of the rollers, the lag screwsof-one roller being journaled in the bar- ,and other arm, plunger brackets connected to the lag; screws mounted in said slots saidgplunger,

brackets having .abutments, rods extending I from the abutments and being slidable in said perforated lugs ,;and coihspnings wound aboutsaid rods between the lugs and abutments.

In ;testimony whereof, I have aflixed my signature [in presence of two I witnesses.
